Timing screws are one of the main mechanisms used in packaging and conveying industrial parts lines. Despite their variety and extensive use, there are few scientific resources on their design principles. This research addresses the design, construction, and performance evaluation of a timing screw mechanism capable of rotating 180 degrees and reversing the direction of the packaging line for cylindrical parts. First, the main design parameters of the timing screw were examined, and their values were set based on assembly requirements. Since the screw is a standard linear-moving screw, extensions were added to enable 180-degree rotation. A computer simulation was used for this process. After determining the dimensions and creating a 3D model of the timing screw and its attached assembly, manufacturing was carried out with thermoplastic polylactic acid using the filament-freeform fabrication method. To evaluate performance, an electric motor was installed on the assembly, and tests were conducted on real parts. The practical tests show that the designed timing screw performs its intended function accurately. Additionally, the average surface roughness measured at 5.34 micrometers is considered a desirable result given the 3D printing process and proper operation.
